Can someone please explain to me why some offenses (UT included) bring everyone in tight on short yardage situations? Its seems to me that the wide receivers are then required to block someone. If they are lined-up wide, a defensive player has to guard them and therefore is taken out of a running play. I would think that offenses would have a better chance of running the ball for a first down if there are at least two receivers in and lined-up wide. What's the logic of having everyone in tight?
